This battery 7,2Ah is for max load up to 50W no more. You can power one LED module of 50W on it, and will light. I use often single 9W warm white led for hand held light. There is LED modules of 100W, 200W 500W,....

See the specifications of the Voltage and current rating of your said LED. Powering a LED is always good with a current controlled source like a driver. You may also use a resistor in series to the LED. Cheers
